pls use small servo deflections during the wizzard. if you use no guardian, these deflections will be used to control rth .... and your turns will end in the "spiral of death". Rabe2002 made a nice video of this, youŽll find it on the first pages of this thread.

sorry Mike ... full servo deflections during the wizzard is only for use with the guardian (rtfm).

cheers Thomas

Read the following from the manual.... You could still end up with a spiral of death if you don't have enough servo deflection.. I emphasized in bold text where the confusion seems to be... IMHO of course..

Mov Rudder/Aileron Stick Left: How much you move the Aileron (or rudder) stick during this menu item depends on whether you are using the
Guardian.
If you are using the Guardian, move the stick all the way to the left (see Guardian manual for more information). If you are not using
Guardian, the following information applies:

Move your Rudder/Aileron stick to the position you use for making a normal left turn. Don’t give more left stick than you would do normally
during flight!The OSD Pro’s RTH function will never exceed the rudder/aileron left turn stick position you set here, or the corresponding right turn position, when it attempts to steer the model. So, the amount of left stick you supply will set the maximum throw of the aileron/rudder during RTH. NOTE: during this step, the OSD Pro also examines the elevator position. If your radio is programmed for elevator aileron mixing, it will be detected during this step, and a proportional amount of up elevator will be applied during RTH turns. If your radio does not do this mixing,
but you desire RTH to provide up elevator when turning, move your elevator stick to the desired amount of climb (corresponding to full
Aileron/rudder stick left) during this step.

· Mov Elev TX STICK Down(Climb): How much you move the Elevator stick during this menu item depends on whether you are using the Guardian. If
you are using the Guardian, move the stick all the way down (see Guardian manual for more information). If you are not using Guardian, the
following information applies:

Move the Elevator stick downwardly, to the position you would use for normal climb. Don’t give more down stick (climb) than you would do
normally during flight! Note that this step results in up-elevator. The OSD Pro’s RTH function will never exceed this elevator up position, or
the corresponding elevator down position, when it attempts to climb or descend the model. So,the amount of down stick you supply will set the maximum throw of the elevator during RTH.

Thomas and Mykro thank you for pointing this out. Indeed I was not using full stick left or up during the servo analysis wizard, since this was stated in the manual, and it seemed to be the best thing to do.

However because the control surfaces deflections were set up to be quite high at maximum stick input, I had to use less than 10% (maybe just 5%) of the available stick input during the servo analysis wizard. Therefore, the servo positions between no deflection and maximum deflection used by the OSD were very few, resulting at low resolution, and making things happen not progressively at all.

I already changed the servo linkages in such a way that I think I will have to use about 50-60% of the full stick deflection next time I run the servo analysis wizard. This can only improve the situation!

The aerobatic capabilities of my plane are now impaired, but you can not have the best of both worlds. Anyway, the more equipment I was adding to this plane, I found that I was doing less and less hammerheads and knife edge passes.

- The voice alerts are very difficult to ear with all the noise from the camera, I would like to turn down the volume from the camera and turn up the volume for the warning alerts, how can I do this? I am using the GOPRO for recording and FPV.

- I have configured the OSD menu with one spare channel on a 3 pos switch in my Futaba 9C to acess all the settings. Sometimes when flying, if the RTH is activated by glitches, or sometimes even whitout RTH activated, the menu comes up in the screen whitout me touching any switch .. can anyone help me on this one?

- Downloaded the Itelemetry app for Iphone and ordered the cable to connect. Just tried it for the first time, but the plane icon does not move, cable connected to the audio exit of Eagle tree video station .. wondering if anyone has a fix for this? The GPS gets the fixing and the coordinates appear on the OSd screen, but on Iphone ... nothing!

- Finally, just wondering if anyone in the forum is flying the EZ Glider with this OSD and Guardian module, can you post the stabilization and RTH settings for me to try it out?

Thanks in advance ... here is my first FPV video with this plane and OSD system:

About the altitude, I think the OSD PRO GPS measures the altitude from above sea level, so the altitude it shows is relative to the sea level.

The GPS altitude data recorded in the eLogger is GPS altitude above sea level. But, the OSD remembers the GPS altitude when the Home position is set and then calculates and displays the altitude above the home reset point. If you're using the pressure altitude expander then the pressure altitude in both the eLogger and OSD is the altitude above the home reset point. I've never gone lower than the reset point but I believe the OSD will display negative altitude.
